S1112 EJMT processor specifications
| Specification | Configuration |
|---|---|
| Catalog model | 9242-21B-EJMT |
| Processor feature | EJMT |
| Physical cores | 4 |
| Sockets | 1 |
| Processor arrangement | One processor module |
| Clock range | 3.6 to 4.0 GHz |
| IBM i software tier | P05 |
| CPW | 117,300 with all listed cores activated |
S1112 EJMT IBM i configuration
IBM i is limited to four virtual processors and 64 GB. Additional physical cores and memory can serve AIX, Linux, or VIOS workloads; they do not increase the IBM i limit.
S1112 EJMT performance
| Thread mode | rPerf |
|---|---|
| Single-thread | 39.9 |
| SMT2 | 81.8 |
| SMT4 | 119.9 |
| SMT8 | 148.8 |
AIX rPerf and IBM i CPW measure different workloads; compare configurations using the appropriate rating.
S1112 memory and storage
| Specification | Configuration |
|---|---|
| Memory slots | Four DDR5 DDIMM slots |
| Memory type | 4000 to 4800 MHz DDR5 |
| IBM i memory | Up to 64 GB |
| Total system memory | Up to 512 GB; configured ceiling requires confirmation |
| Internal NVMe | Four U.2 bays; up to 12.8 TB raw |
| IBM i mirrored storage | Up to 6.4 TB |
The family AIX/Linux specification also states 256 GB. We will confirm the system ceiling and module population in your quote.
S1112 memory and NVMe part numbers
Match the catalog code, part number, and feature when ordering memory. NVMe features differ for IBM i and AIX/Linux even when drive capacity is the same.
| Catalog code | Capacity | Part number | Feature |
|---|---|---|---|
| 32A1 | 64 GB (2 x 32 GB) | 03HD880 | EM54 |
| 32A2 | 128 GB (2 x 64 GB) | 03HD896 | EM5B |
| 3298 | 256 GB (2 x 128 GB) | 03HD815 | EM5V |
| Catalog code | Drive size | IBM i feature | AIX/Linux feature |
|---|---|---|---|
| 594D | 800 GB | EC7Y | EC7W |
| 5951 | 1.6 TB | ECT4 | ECT0 |
| 5952 | 3.2 TB | ECT5 | ECT1 |
Memory-module capacity does not change the 64 GB IBM i limit. Match paired modules to the operating systems and slot population.
S1112 I/O and physical specifications
| Specification | Configuration |
|---|---|

Include your operating-system release and current PTF level so we can confirm the installation requirements.
Compare S1112 processor configurations
EJMT keeps IBM i in P05; EJSV moves to P10 and adds physical cores for AIX or Linux. Both configurations have the same IBM i processor and memory limits.
